Difficulty: Easy
Correct Answer: Alluvial soils
Explanation:
Introduction / Context:
Different soil types support different kinds of crops and agricultural practices. In Indian geography, questions frequently ask which soils are most suitable for agriculture because this affects crop patterns, irrigation practices, and population distribution. Alluvial soils in particular are associated with the fertile plains of major rivers and are a key reason why certain regions are densely cultivated.
Given Data / Assumptions:
Concept / Approach:
Alluvial soils are formed by the deposition of sediments by rivers. In India, the Indo Gangetic and Brahmaputra plains are covered with alluvial soils that are rich in minerals, have good texture, and respond well to irrigation and fertilisers. These soils support a wide variety of crops, including rice, wheat, sugarcane, and pulses. Red soils can be productive with inputs but are generally less fertile than alluvium. Sandy soils drain quickly and are poor in nutrients, while peaty soils are limited and often acidic. Therefore, alluvial soils are generally considered the most suitable for intensive agriculture.
Step-by-Step Solution:
Verification / Alternative check:
Standard geography books describe the Indo Gangetic plain as the food bowl of India and link this directly to the presence of fertile alluvial soils and adequate irrigation. Crop production statistics show that these areas produce a large share of the country's cereals. In contrast, regions dominated by sandy desert soils or peat are either sparsely cultivated or used for specialised crops only. This evidence supports the conclusion that alluvial soils are most suitable for agriculture in the broad sense.
Why Other Options Are Wrong:
Common Pitfalls:
Some learners may over interpret the phrase suitable for agriculture and think that all listed soils must be useful in some way, leading to confusion. Others might recall that red soils are widely spread and mistakenly choose them. The key is to focus on large scale, intensive, multi crop agriculture, which is best supported by alluvial soils in river plains.
Final Answer:
The soil type generally considered most suitable for intensive agriculture in India is alluvial soils.
